The coefficient for (7y) is 7. In an algebraic expression, the coefficient is the numerical factor that multiplies the variable, which in this case is (y). Therefore, 7 is the coefficient of (y) in the term (7y).
The sum of 4x and 7y in algebraic expression is written as (4x + 7y). This expression represents the combination of the two terms, where 4x is the coefficient of x and 7y is the coefficient of y. There are no like terms to combine further, so the expression remains as it is.
6x2 - 4x (6/2)x2 - (4/2)x = 3x2 - 2x ========
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
14y - 2x = 28 ie 7y - x = 14 ie 7y = x + 14 or y = (1/7)x + 14 The slope is the coefficient of x, or 1/7
7y-42=28 ==> 7y=42+28 => y=70/7. => 10
Well, honey, the coefficient of 7y is simply 7. It's like asking how many slices of cheesecake Betty White wants - she only wants one, just like there's only one coefficient in front of that y. So, in this case, the coefficient of 7y is just good ol' 7.
The sum of 4x and 7y in algebraic expression is written as (4x + 7y). This expression represents the combination of the two terms, where 4x is the coefficient of x and 7y is the coefficient of y. There are no like terms to combine further, so the expression remains as it is.

if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
14y - 2x = 28 ie 7y - x = 14 ie 7y = x + 14 or y = (1/7)x + 14 The slope is the coefficient of x, or 1/7
Oh, dude, like, a numeral coefficient is a number that multiplies a variable, you know, like 5x or 7y. On the other hand, a literal coefficient is a coefficient that contains a letter or a variable, like 3a or 4b. So, one's just a number, and the other's a number with a side of alphabet soup.
7y-42=28 ==> 7y=42+28 => y=70/7. => 10
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
16+7y-8 = 7y+16-8 = 7y+8
